SHUTTER-BOLT.

SPECIFICATION tamin part of Letters Patent No. 643,910, dated February 20, 1900.

Application filed January 5, 1900. Serial No. 425. (No model.)

To all whom it mcty concern.-

Be it known that I, J OHN SABOLD, a citizen of the United States, residing at Boyertown, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Shutter-Bolts, of which the following is a specification.

This invention relates to certain improve ments in the construction of shutter-bolts of that class which serve the double purpose of lockin g the two shutters in the closed position and of holding the two shutters in a partlyopen position.

My invention is an improvement on the shutter-bolt for which Letters Patent of the United States were granted September 10, 1861, No. 33,266.

In the drawings, Figure 1 is an inside view of a pair of shutters having the improved bolt attached. Fig. 2 is a horizontal section of the shutters in a partly open or bowed posi- Fig. 3

shell or socket in which it slides, as seen from the reverse side to that shown in Fig. 1. Fig. 4 is a top edge View of the bolt which is to be on one shutter and showing its tapered end in the socket that is to be secured on the other shutter. Figs. 5 and 6 are sectional views of the socket into which the end of the bolt is to be entered. Fig. 7 is a cross-section of the bolt at the knob.

The letters A A designate the two windowshutters, and h the window-frame to which they are hinged.

The socket O, which receives the end of the bolt, is secured to the shutter A. This socket at the entrance end and at the bottom has a flange 6, provided with a hole e, to receive a down-pointing hook or lip d on the end of the bolt, and thereby hold the two shutters in a partly-open position, as in Fig. 2. This socket also has on its inner side confronting the shutter a vertical bead f at the final or terminal end, (see Fig. 6,) and a flange 9 beyond said terminal end affords bearing-surface for the end of the bolt when the latter is shot to its fullest extent, at which time the vertical bead f binds against the outer tapered or beveled surface a on the bolt, and thereby the projected or shot bolt is caused to fit tightly within the socket G,

and thus prevents all loose vibration or rattle of the closed shutters. A stop-lugt'is on the flange g, and the end of the bolt abuts against the stop-lug, as in Fig. 1.

the shutter A. longitudinal slot 7', a bolt open'ing 70 at the front end, and a bolt-opening k at the back end. The bolt F is'a straight bar along its upper edge from one end to the other. Its lower edge 1 is also straight for about fivesixths of its length, but its projecting end is broader in the vertical direction for about one sixth of the length of the bolt, such broader portion projecting downward, as at Z. A notch m is in the lower edge of this broad part and forms the hook or lip 61 already referred to. I provide on the lower edge of the bolt an inclined edge 0 to connect the straight narrow part Zwith the broader down-projecting part Z, so-.that when the bolt is moved endwise backward to retract its projecting end within its shell the said inclined edge 0 will automatically raise the end and the bolt may be entirely drawn back. Again, this incline 0 serves to automatically lower the bolt end as it is drawn out endwise at the time of engaging its hook'or lip din the hole a. This latter operation is as follows: The shutters are to be j ust enough to place the point of hook or lip d over the hole e, so as to slightly engage. Then the shutters are to be spread or bowed farther. The effect will be to draw the bolt outward, and the moment it is so drawn the incline 0 will allow the drawn-out bolt end to lower, and said hook or lip will thereby fully engage with the hole e. t

On the inside of the shell or socket G, at the back end, is a bottom inclined slideway p, the high end of which is at the bolt-opening it. When the bolt is drawn out endwise to its fullest extent, (see Fig. 3,) as maybe the case when it is holding the two shutters in a partlyopen position, the rear end q of the bolt will be inside of the shell and at the low end of the inclined slideway 1). The vertical width of the shell or socket G on its interior is so much greater than the width of the bolt F thata certain amount of up-and-down movement will be afforded the bolt. This inclined slideway 19 therefore serves when retracting the bolt The bolt F and its shell or socket G are on The shell at the front has a slightly bowed and the bolt slid out a little,

to guide the rear end 13 of the bolt out of the bolt-opening 70. A lug o is provided on the inside and bottom of the shell or socket near its center, on which the bolt F may rest when it is drawn out, as in Fig. 3, to prevent said rear end from tilting down while the bolt is resting on the bottom bearing 3 at the front bolt-opening 7t and by such tilting down accidentally lift the hook or lip d out of engagement with the hole 6.

The bolt has a flat knobt to be grasped by the fingers when it is desired to slide the bolt. The knob has a round shank 25' next to the bolt, on which a button u is loose to be oscillated, a lever a being attached to the button. The fiat knob Z and round shank Z have the shape of a T. On its front face the button it has two \vedgeshaped cams 0, one reversely inclined from the other. The button is broad enough to fully lap over or entirely across the longitudinal slot-j of the socket G. The two reverse wedge-shaped cams U when turned one way take under the head 25 of the flat knob and tighten the bolt to fixed position. IVhen the button 11. is turned the other way, the wedge-cams are moved from under the flat knob and then the bolt is loose.

There is nothing on the socket 0, directly over the flange c, to prevent the end of the bolt from up-and-down movement.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a shutter-bolt the combination of a socket, O, to be secured to one shutter and having at its entrance end and bottom afiange, 6, provided with a hole, 6, and also provided with a vertical bead, f, on the inner side at the final or terminal end; and a sliding bolt to be secured on the other shuttle-said bolt having a straight lower edge, Z, along its entire length except its projecting end which is broader in the vertical direction and projects downward and said broader and having a straight lower edge, Z, in a different plane from the other lower edge, Z, and an inclined edge, 0, connecting the said two lower edges, and also provided with a notch, m, and a hook or lip, cZ, the broader end having its outer surface beveled or tapered.

2. The herein-described shutter-bolt having a straight upper edge from one end to the other, a straight lower edge, Z, along its entire length except at one end which latter is broader than the other parts of the bolt, and the lower edge, Z, of the broader part being in a different plane from the other lower edge, an inclined edge, 0, connecting the said two lower edges, and the broader part provided in its lower edge with a notch which forms a hook or lip, d, at the extremity.

3. In a shutter-bolt, the combination of a shell or socket, G, having a front longitudinal slot, j, a bolt-opening, 70, at the front end, a bolt-opening, 70, at the back end, and a bottom inclined slideway, 19, whose high part is at said back end bolt-opening; a sliding bolt movable in said bolt-openings and having a limited up-and-down movement and provided with a flat T-knob having a round shank; and a button loose on said shank and provided on its front exterior face with two wedge-shaped cams, 11, one reversely inclined from the other and both cams taking under the head of said flat head.

In testimony whereof I afiix my signature in the presence of two witnesses.

JOHN SABOLD.
